STEREOTYPE OR MATRIX MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 331,438, dated December 1, 1885.

Application filed August 29, 1884. Serial No. 141,753. (No model.)

To all whom it may concern:

Be it known that I, J. LANE POALK, a citi zen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Stereotype or Matrix Making Machines, of which the following is a specification.

My invention relates to stereotype or matrix machines, and has for its object to produce a simple and cheap machine that can be easily operated and will not be liable to get out of order, and one that is adapted to many and varied uses; and to these ends my invention consists in a machine constructed as more particularly pointed out hereinafter and claimed.

Referring to the accompanying drawings, forming part of this specification, Figure 1 is a side View of a machine involving my invention. Fig. 2 is a plan view, and Fig. 3 is a side View, of the dial and pointer.

From a suitable base, A, at one end rises the standard B, supporting a shaft, 6, to which is pivoted an arm or frame, 0, carrying a shaft, 0. Upon this shaft is supported a roll or cylinder, D, to the periphery of which are attached the various types or dies d. Upon the frame is fixed an indicator or dial, E, having the various characters upon its face, and through its center projects one end of the shaft 0, to which is rigidly secured a pointer, F, having a suitable handle. The dial may be provided with notches or recesses e, corresponding to the various characters on its face, and the pointer may have a projection or lug, f, adapted to fit into these recesses, to insure the proper register or location of the pointer and the corresponding type on the cylinder; also, secured to the shaft 0 and rotating with it is an eccentric or cam, G, and against the periphery of the cam bears one end of a slide, H, the extreme end h of which is pivoted, so as to turn in one direction and be rigidin the other; also, supported on the base A is a bed, I, carrying a sliding plate, K, upon which is placed the mold or matrix-forming material J. This bed is adapted to be moved lengthwise of the machine by any suitable means at each impression of the type or die wheel, and the plate K is fitted in suitable bearings, as P, in which it is moved transversely of the machine by proper mechanism, to form the line-spaces, a hand-wheel, M, being shown attached to a screw-shaft, m,-working in the having a downwardly-extending foot or toe, o,

resting upon the base A. In a bearing at the top of the lever is pivoted a weighted or other suitable pawl or clutch device, P, the end of which bears upon the wheel or pulley n. Across the front part of the upper end of the lever is a bar or strip, g, having an inclined or beveled surface in position to be struck by the pivoted end h of the slide H in its downward movement and cause the said end to turn upward, so as to pass by it; but when the lever is raised the pivoted end impinges upon the inclined face of the bar 9, and the lever O is forced backward, carrying the pawl or clutch with it, and causing it to grasp the strap or band B, connected to the bed and passing over the pulley, and to feed the bed forward the required distance. The lever is returned to its normal position by any suitable mechanism, as a spring, on, and foot 0 serves as a gage to control the extent of the return movement and to cause the strip 9 to assume its proper position to be struck, as hereinafter explained.

The arm or lever C may be held in its normal position by a spring, and may be depressed by hand or other suitable means.

The typewheel may be of any desired construction, and may have any number of kinds of characters on its periphery, and they may be arranged in any order or series.

Such being the preferred construction of the device, the operation will be readily understood.

The material to be impressed is placed upon the bed, and the pointer F is turned to the de sired character on the indicator-wheel, which will bring the corresponding type or die into printing position over the bed. The lever O is now depressed by hand or foot power, and the impression made in the matrix material. The rotation of the type-wheel carries the eccentric or cam with it, and this is so arranged that it will push the slide H outward more or less, in accordance with the width of the face of the type to be impressed. On the downward movement of the lever G the pivoted end of the slide is moved upward by contact with the inclined plane, and has no effect upon the pawl or clutch but in its upward movement it bears more or less upon the inclined face of the strip, and forces it backward, so as to grip the strap or tape B, passing over the pulley n, and feed the bed along the distance required to allow of the printing or impressing the desired letter and the necessary space between it and the next letter. The pointer is then turned to the next letter desired, carrying the type-wheel and eccentric with it, the latter moving the slide forward in accordance with the width of the next character to be printed or impressed, and the impression is made, the bed being again fed the required distance. When the line is completed, the bed may be retracted by hand or a spring to its normal position, and the handwheel being turned the bed is fed sidewise the distance of a line-space, and the opera-' tion repeated.

It will thus be seen that by the above-described simple and economical arrangement I have produced a stereotyping-machine that can be easily and rapidly used, and that produces the desired and necessary variable spacing.

It is evident that the principal features of my machine can be used in a type-writer with equal facility, and that it may be modified in its details to a considerable extent without departing from the spirit of my invention; and I do not therefore limit myself to the construction shown and described.

It is evident that the dial might be fixed to .the shaft and the pointer be secured to the frame,if desired but I prefer the arrangement shown.

What I claim is 1. The combination, with a movable arm carrying a rotating type or die wheel, of an eccentric moving therewith and a variable feeding device, substantially as described,controlled by'the eccentric.

2. "The '1 combination, with a movable arm carrying a rotating type or die wheel, of an eccentric moving therewith, a variable feeding device, substantially as described, and a slide operated by the eccentric and operating the feed device.

3.- The combination, with a moving arm carrying a type or die wheel and an eccentric connected to the latter, of a slide bearing against the eccentric and a pawl or clutch 0perated by the slide, substantially as described.

4. The combination of a pawl or clutch, an arm carrying a type-wheel, and a slide for operating the pawl or clutch having a pivoted finger or end, and a cam or eccentric for controlling the slide, whereby the clutch may be moved more or less in accordance with the position of the type-wheel, substantially as set forth.

5. The combination, with a movable bed, of a pulley or wheel supporting a band or cord attached to the bed, a pivoted lever having a toe or stop for supporting it in its normal position, and a clutch carried by the lever and engaging the band, substantially as described.

6. The combination, with a matrix-bed, a pulley or wheel, and bands between the bed and wheel, of a pivoted lever carrying a clutch engaging with the wheel, a strip or bar attached to the lever, and an oscillating slide for operating the lever,having a pivoted end, whereby the bed is moved step by step, substantially as described.

7. The combination, with a movable bed carrying a matrix or plate, of a pivoted lever carrying a type or die Wheel, an indicator carried by the lever, a pointer connected to the type-wheel, an eccentric carried by the lever, and means, substantially as described, whereby the bed may be moved in accordance with the character to be impressed to produce Variable spacing, as set forth. I

8. The combination, with a movable bed carrying a matrix or plate, of the type or die wheel supported in a moving frame, an indicator connected with the frame, a pointer for adjusting the wheel, a cam connected to the Wheel, a slide bearing against the cam, and the feed devices, substantially as described, whereby the position of the cam will control the feed of the bed, as set forth. 9. The combination, with a bed-carrying matrix, of a clutch supported on a lever, connections between the bed and clutch, a strip or projection on the lever having an inclined face, and an arm carrying the type-wheel and having a pivoted end, the arrangement being such that the pivoted end does not operate the lever in its movement in one'dir'ection but does in: the 1 other, 'substantiall'y'as described. In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
